Seeing all these mods make me so excited to play this game again. I still play it on my ipad and computer, but knowing these mods exist... so excited. ;-;
That's not a bad thought! It would work, but I think you wouldn't get any lines (even at 1 guest per maze). Using a ride like this, it's easier to control how long the waits are.
You definitely could do that. Unfortunately, since the peeps still have to get on the ride, I don't think there's a good way to avoid them phasing into the wall. But I'd be happy to be proven wrong!
I just went into OpenRCT2 to test this very idea, and it does work. They do phase into the wall of course, but if you offset the exits so that the exit for a station is placed on the entrance of the previous station, then any guest that enters a queue line will also exit from the same queue line after a few seconds. Not perfect, but it does mean that guests get in line, walk up, and leave from the same window they walked up to.
I wonder how doable this is in Theme Parkitect, even if you don't have access to a tile inspector. I gotta give it a try there. It'd also be interesting to see metal detectors/bag checking done the same way too where guests are funneled and stopped at each checkpoint.
